Python List Slicing with None as argument

Question

Via trial and error I found out that

my_list = range(10)
my_list[:None] == my_list[:]

I use this for django query sets so I can define a si

Answer 1

It should be safe. In Python, something[] is equivalent to something[slice(...)], and the documentation for the slice type clearly indicates that the arguments for stop and step default to None.
